6. CIRCUIT DESCRIPTIONS
Equalizer Amplifier
  The equalizer amp uses a low-noise IC (NJM
4558DX) that contains both the left and right
channel circuits. This IC uses a balanced positive/
negative power supply to permit the more than
sufficient permissible input level of 150mV (at
1kHz, 0.017dTHD).
PowerAmplifier
   This all-stage direct-coupled pure complemen-
tary SEPP circut features a differential amplifier
in the first stage, and incorporates the tone con-
trol circuits in the NFB loop.
   The power stage is a complementary 2-stage
Darlington connection, resulting in an output
power rating of 35W+35W (8Sr, 20Hz-20kHz),
harmonic distortion of lessthan O.O\Vy.
